ColdFusion Method

Question

I am sending the value of a variable from the http url to another cfm page, but I'm not sure how to get this value on another page. In php we use $_GET['variable']; I'm not sure what is equivalent to this in ColdFusion.

Answer 1

ColdFusion has the ability to access these variables very similar to what you do in PHP:

PHP:

$foo = $_GET['variablename'];
$bar = $_POST['variablename'];

CFScript:

foo = URL['variablename'];
bar = FORM['variablename'];

CFML:

<cfset foo = URL['variablename']>
<cfset bar = FORM['variablename']>

:

<form name="main" action="handler.cfm" method="post">
  <input type="text" name="conFUSion" value="abc" />
  <input type="text" name="CONfusion" value="def" />
  <input type="submit" name="Submit" />
</form>

:

gethttprequestdata().content , , :

conFUSion=abc&CONfusion=def&Submit=Submit

ColdFusion , . java.util.HashMap, ColdFusion, :

arFormscope = gethttprequestdata().content.split('&');
cs_form = createobject('java','java.util.HashMap').init();
for( i=1; i<=arraylen(arFormscope); i++ ){
  arElement = arFormscope[i].split('=');
  key = arElement[1];
  value = arElement[2];
  cs_form[key] = value;
}

- cs_form, :

... , :

cs_form['CONfusion']; // def
cs_form['conFUSion']; // abc
cs_form['CONFUSION']; // Error, undefined in java.util.HashMap

Answer 2

#URL.variable# GET. #FORM.variable# POST.

Answer 4

You can access them using #url.variable#. For example, in PHP you may have $_GET['id'], and in CF you will have#url.id#

Answer 5

I have done this in ColdFusion 7 before.

You can use the value of cgi.query_string to get the query string and then split like this:

httpGetValues = createobject('java','java.util.HashMap').init();

nameValuePairs = cgi.query_string.split('&');
for( i=1; i lte arraylen(nameValuePairs); i = i + 1 ){
    pair= nameValuePairs[i].split('=');
    key = URLDecode(pair[1], "UTF-8");
    value = URLDecode(pair[2], "UTF-8");
    httpGetValues[key] = value;
}

Make sure you decode the values.
